When I tried out of the box at 4.4, everything was set to auto including the voltage, I just changed the multi to 44. The auto setting bumped it up to 1.35v or so, the chip hit 80c in Prime 95, and I smelled hot electronics when I left and came back into the room.

Try setting the voltage to 1.27 and speed at 4.2 ... re-boot and then go back into BIOS and set it to 4.4 or 4.5 see what happens.

You're on BIOS F14?

Yes it came with llike F5 but i flashed it to newest,maybe because im runnings slightly tight memory timings?

Well if the cpu OC dosent play nice with the memory OC ill just stay at 4.5 since i gain more performance that way.
Also its wierd that you could smell something at 80c+, when my cpu had 1.44v running through it in intel burn test it was touching 101,102c on a few cores and i didnt smell a thing.

I'm suspecting the IHS is a big wildcard in overclocking. If my chip wasn't doing as well as it is, I was planning on de-lidding. That was one of the reasons I didn't go for the Intel warrantee. The other was the chip cost well under $200.

Yea, the CM 212 Evo fan was running at full blast. I have the voltages as low as they'll go to be stable at that speed. It'll eventually be in a watercooled HAF 932 case, but I suspect it won't help me get past that speed at the same voltage.

Thanks, I'm pleased... and really interested to see it under H2O. I have a feeling I won't get to that till the holiday is behind us.

The only thing I adjusted in BIOS was the VCore and multi. I'm still trying to figure out how to get VCore to drop back to normal when it's idling. When I set manually, it's stuck there. Someone mentioned a way to do it. I still don't understand VID and load line calibration and all that.

The G.Skill sniper memory I got is great stuff. Once I get the BIOS/CPU all figured out, I'm going to try pushing that, I suspect I'll get near 2500 or more with relaxed timings.

Like Jack said wait a few days and the temps will drop its normal.
Going to buy for christmas 3570K and the same cooler so this thread is very useful to me.
Hope you can overclock it to 4,5~4,7 with nice temps using the CM 212 EVO.

He doesn't have to wait a few days. He may gain 1 to 2 degrees. The CPU is ready to rock.

Sasqui, you're having a good OC experience with Z77X-UD5H? Easy to use?

Recently bought the parts for a new rig and besides the review made on TPU, i did not ask to any person about the OC potential this board has. I'll OC a 3770K with a H100... so i'll probably get better temps, but that does not change the OC experience with the board (i guess).
